Attendance and Class Expectations:
Here are a few guidelines for the semester
• An attendance will be taken beginning of each class meeting, as accurate attendance records
are required. Although there is no grade for attendance, Physics I is a class that moves at a
fairly rapid pace so there is a lot of information passed on in every class meeting. If you
miss, please make arrangement with someone in the class to obtain the information from that
class. Also, please refer to individual sections regarding makeup of missed classwork.
• As a school policy, I can no longer withdraw a student for non-attendance. Therefore, if you
stop coming to class, it is your responsibility to withdraw from this course. If you remain on
the roll at the end of the semester, you will have to receive a letter grade (that you probably
will not enjoy).
• Labs and Homework assignments are due at the beginning of the class period. Any
assignments turned in after this point will be considered late.
• Excused absences consist of illness (your own or an immediate family member), family
emergency, inclement weather, military duty, and jury duty or other extenuating
circumstances. You will be allowed and expected to make up work missed due to such
absences. Please notify me prior to the absence in applicable cases or as soon as possible
after the absence so that arrangements can be made. Documentation of some sort is expected
to verify such absences.
• Unexcused absences will result in work missed being counted as late. Late work is discussed
later in the appropriate section.
• I realize that many of you may work and there may on occasion be extenuating circumstances
due to your employment. However, since you are enrolled in this course, you know the
scheduling constraints. Therefore, 1 work-related absence per semester will be allowed as
excused. Subsequent absences will be unexcused.
• Work will always be accepted early!
• Please ask if you have questions during class! Even though you may feel that you are the
only one not understanding something, chances are most people would benefit from have a
point of confusion explained again.
Academic misconduct (cheating):
DO NOT CHEAT!!!! Do your own work, don’t share information on exams, etc. Just don’t do
it! It is disrespectful to your school, your classmates, yourself, and especially an affront to your
teacher. If you are caught cheating, an incident report will be filed with the dean and
consequences will follow according to the guidelines set forth by the College. Cheating is a very
serious offense and can result in failure in the course.
Exams:
The exams are closed book, closed note, unless otherwise stated. I will assign a maximum point
value for each problem or question on the unit assessments. Written tests will normally be
completed during class meeting hours on scheduled dates and announced in class. Pocket
calculators are allowed, but you cannot share them. Programmable calculators are not allowed
unless the memory is cleared out. Since I will be assigning partial credit on some problems, you
must present complete, clear solutions to the problems, and show all of your work. Legibility is
important: if your cannot be easily decyphered it might receive no credit. To receive all credit for
your solution also please be certain to answer in the appropriate units. Questions are permitted
during the exam and if something is not clear please ask!
If an exam is missed without a valid excuse, the exam must be taken in the test center
within 4 calendar days and with a penalty of 5% per day, (minimum 10% loss). With a valid
excuse, please take the exam within 5 calendar days. Exams will be placed in the test center on
the same day as the test if I notice anybody missing.
A score of 60% mastery is required on all unit material. If you score less than 60% on an exam,
you will be required to retest within two weeks. The maximum score on a retest is 60% and the
retest score will replace the previous grade, regardless if it is higher or lower. You may only
retest once on each unit. Because the material tends to be cumulative, a student who takes a
retest but again scores below 60% will be requested to withdraw from the class and try again
later.
All class exams are equally weighted, since each is worth 100% regardless of actual point value.
Homework:
Homework will be assigned for each unit. These problems will be collected at the exams and
checked for completeness. A complete homework assignment will receive 10 points. It is
important that you at least attempt the problems, even if you have difficulty with them.
Practice makes perfect and that especially applies to solving Physics problems. It is fine to
form study groups with other students, as long as you really learning and not simply getting
answers from others. Late homework that is turned in after you hand in your exam will receive
half credit.
Labs:
All labs will be conducted as group on Mondays. Once you have completed the experiment, you
will analyze the data and prepare a lab report to submit for grading. You are strongly encouraged
to start analyzing your data before leaving lab so that help is readily available if a problem
arises! Your data sheet must be checked and initialed by the instructor before leaving
lab. This helps ensure that you have reasonable data. Instructions on how to prepare an
appropriate lab write up are included in the lab manual. Also, instructions on how to prepared
suitable tables and graphs are in the manual. There is very specific graph paper required for this
course. Please use this type of paper or your graphs will be penalized. Please make sure to
include the purpose of the experiment, answer the questions in complete, logical sentences, and
include all units where necessary. If you are in doubt about your report, please ask. It is better
to ask a question, even if you think that it is silly, than to lose points! Lab partners are allowed
but not required. Each student must collect and analyze the data and submit a written report
independently (i.e., your data should be your own, not a copy of your partner’s data, unless
specifically allowed by the instructor). Labs will be graded on a scale of 1 to 10 and the score is
included in the course grade.
If you miss a lab with an excused absence, you must make up the lab independently. (An
unexcused absence will result in an automatic late penalty.) However, you must get a written
permission slip before going to the science center to perform the lab! The independent lab
setups are available for a short time only, so you should sign up ASAP or be forced to wait until
the end of the semester (and suffer point loss).
Lab due dates are on the schedule provided. Late work will be penalized 1 point per
week, and labs that are over 2 weeks late will receive no grade but must still be completed.
Grading:
Your grade will depend solely on the quality of your work! You are not competing against the
other people in this class.
Exams 70%
Labs 20%
Homework and “Board Points” 10%
A
B
C
D
90-100% of total points
80-89%
70-79%
60-69%
There will be no curve, and no outside-class extra credit assignments will be given.
To determine your grade use the following method:
A. Take each test score and divide by the points possible, which gives you the %. Add your
test % up and divide this number by the number of exams. Multiply this number by 70.
This is your total exam % out of 70
B. Divide each lab score by 10 (or 30 for mastery lab), which gives you the %. Add your lab %
up and divide by the number of labs. Multiply by 20 and this is your lab %
C. Divide each hw score by 10, again getting the %. Add them up and divide by the number of
hw assignments and multiply by 10, which give you hw%
D. Add these 3 % together, and you have your current % in the class.
Office Hours:
I will try to set my office hours for maximum availability to students. You may contact me in
person, via the telephone or via email during these times. Also, you may contact me via email
pretty much any time. Please make use of my office hours! I am there to help you!

OKLAHOMA CITY COMMUNITY COLLEGE LABORATORY SAFETY
Oklahoma City Community College science laboratories exist to provide you with the
opportunity to learn. Whether you do your lab work in a group lab (GP) or individually paced
through the Science Center, the same laboratory rules and safety precautions apply. Always
follow the instructions given by your instructor/laboratory supervisor.
Some labs require the sharing of equipment and materials. If you should inadvertently break or
remove from the laboratory a piece of equipment, you may be preventing other students from
completing their lab work. We ask that you exercise care and consideration when handling
laboratory equipment.
When you choose the individual pacing (IP) option, you may find yourself working with less
supervision. This means that you have a greater responsibility for safety - not only your own,
but the safety of others. It is very important that you observe all safety regulations, and help
others to do so as well. Please don't think of the laboratory as recreation. Have a productive time
learning, but remember THERE ARE HAZARDS WHICH COULD RESULT IN SERIOUS
INJURY.
Read the following safety regulations and then indicate with your signature that you understand
and agree to comply before beginning any laboratory work.
LABORATORY RULES AND SAFETY PRECAUTIONS
1. Do not enter the laboratory when an instructor/lab supervisor is not present, the lab door is
closed, or a chain is across the entrance. Finish your lab work in time to clean up before the
end of the scheduled lab period.
2. Use an approved disinfectant to clean your lab station at the beginning and end of each lab as
directed by the instructor/lab supervisor.
3. Perform only authorized experiments. You must be enrolled in a class with a lab to perform
lab work. Children, friends or visitors are not permitted to be with you while you do your lab
work.
4. Wear personal protective equipment (PPE) when instructed to do so by your
instructor/laboratory procedures or your lab supervisor. When required, the PPE should also
be worn when cleaning up following an experiment.
5. Eating, drinking, mouth rinsing, applying cosmetics or lip balm or handling contact lenses is
prohibited in the Science Center or group lab areas.
6. Shoes which offer reasonable protection will be worn while in the laboratory. Sandals are not
acceptable footwear in the chemistry laboratory.
7. Be considerate of others working in the laboratory. Do not distract others while conducting
experiments or accomplishing lab activities. When finished with equipment or materials to be
shared with others, make them available to others as quickly as possible.
8. Clean all equipment, glassware and the work area you have been using and return them to
their proper places in the laboratory before leaving the lab.
9. Know the location and proper use of safety equipment in the laboratory.
10.
Immediately notify the lab supervisor of chemical spills, broken glass or other hazards.
Do not attempt to clean up such mishaps/materials by yourself without first alerting
your instructor/lab supervisor.
11.
Immediately notify the instructor/lab supervisor of any accidents, injuries, or
situations in which exposure to human blood or other potentially infectious materials
in the laboratory regardless of how minor they may appear to be.
12. Apply Universal Precautions and Body-Substance Isolation infection control procedures
when appropriate to minimize potential exposure to bloodborne pathogens.
13.
You may be exposed to potentially hazardous materials in the process of completing
your required laboratory activities. Persons with specific health concerns such as expectant
mothers, wearers of contact lenses, persons with known hypersensitivities, etc. should
consult their personal physician for advisement about potential risks before enrollment in the
course.
14. Before doing any laboratory work in group labs or in the Science Center, view the
video on lab safety including bloodborne pathogen precautions and successfully
complete the safety exam.
15. In case of an emergency, think prior to aiding a fellow person in distress. Notify your
instructor/lab supervisor first. If you then choose to assist an injured person, provide
yourself with protection from blood or other potentially infectious materials. If possible
exposure occurs, ask for a copy of the incident report and consult with your personal
physician.
